Each year, the Global Footprint Network measures when "when humanity's demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year." This is measured based on the needs and use of our global population, but the Global Footprint Network also breaks this down by country.
This year, Overshoot Day in the United States was March 13. Our population growth is straining our natural resources and threatening biodiversity. As long as our population continues to grow due to immigration, which can be attributed primarily to Congress's immigration policies, our environmental woes will only be further exacerbated.
